APPARATUS FOR EXTINGUISHING SPARKS FROM SHODDY AND THE LIKE.

Specification of Letters Patent.

Patented Jan. 21, 1913.

Application filed May 6, 1910. Serial No. 559,861.

To all whom t may concern:

Be it known that I, PAUL Nono-x, a citizen of the United States,residing at Holden, in the county of Worcester and Commonwealth ofMassachusetts, have invented a new and useful Improvement in Apparatusfor Extinguishing Sparks from Shoddy and the Like, of which thelfollowing is a specification, accompanied by drawings forming a part ofthe same.

My invention relates to an apparatus for extinguishing sparks fromshoddy and like materials and consists in compressing the same bycausing it to pass between rotating rollers, and has for its object tosmother any sparks which may be present in said material.

Referring to the drawings, Figure l is a front vertical sectional viewon the broken line m-, Fig. 3. Fig. 2 is a side view of the apparatus.Fig. 3 is a top view of Fig. 2.

Similar reference characters refer to similar parts in the differentiigures.

In the drawings the material is introduced into my apparatus through apipe a, and falls into a chamber c open atthe bottom and with its sidescomposed of screening material. lVhile passing through the chamber 0 thedust is removed by means of the exhaust fan b and the material thenfalls into the hopper d. Near the bottom of the hopper CZ and inadjustable proximity to each other are a pair of rollers f journaled inthe frame of the apparatus and rotated in opposite directions, asindicated by the arrows, by means of the chain wheel g and the gears h.In order to separate and disintegrate the material so that it will passreadily between the rollers f, and will not collect thereon, I place awinged roller e j ournaled in the frame of the apparatus and rotated inthe direction of the arrow by the chain wheel t'. The wing on thisroller c, as clearly indicated in Figs. 2 and 3, extends in the form ofa spiral along the surface of the roller. This peculiar shape of thewing causes the material which it acts upon not only to be properlydisintegrated, but also to be spread evenly along the length of therolls so that it will not pass between the spark extinguishing rolls fin bunches. A bunch of material passing between the rolls f would tendto spread them so as to leave a space at some other pointthrough whichsmaller quantities of material might pass without being suthcientlycompressed to smother any sparks present therein. The material thenpasses between the rollers f and is sufiiciently compressed toextinguish all sparks which it contains and, by means of a blower 7c, isdischarged through the pipe Z into a hopper m from which it falls intothe press n.

Variable space between the rollers adaptable to various materials may beobtained by the usual screw adjustment.

I d o not confine my invention to a single pair of rollers, but, ifdesired, a series or train of rollers may be employed.

I claim:

1. An apparatus for extinguishing sparks in shoddy or similar material,including a pair of parallel spark extinguishing rollers with theirperipheries in proximity, means for rotating these rollers in oppositeydirections, a rotatable winged roller above said spark extinguishingrollers for disintegrating the material, and a hopper for conducting thematerial to said rollers.

2. An apparatus for extinguishing sparks in shoddy or similar material,including a pair of parallel spark extinguishing rollers with theirperipheries in proximity, means for rotating these rollers in oppositedirections, a rotatable roller above said spark extinguishing rollers,said last named roller carrying a spiral wing for disintegrating thematerial, and a hopper for conducting the material to said rollers.

S. An apparatus for extinguishing sparks in shoddy or similar material,including a pair of parallel sparkextinguishing rollers with theirperipheries in proximity, means for rotating the rollers in oppositedirections, means above said spark extinguishing rollers fordisintegrating the material, and a hopper for conducting the material tothe rollers and disintegrating means.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
